You
will be able to pinpoint the position of the substring in which you are interested by using one
of the string objects.
1#
Write a program that allows users to choose from one of three shapes: Squares, Circles or (right)
Triangles. Allow the user to use the first letter of the shape (S, C, T) to specify what they want. After the
shape is selected, ask the user for the appropriate data to calculate the shape's area, and then and print
that area value to the screen for them.
Area formulas you can use:
Triangle: % base x height
Square: length x length
Circle: % Pl x radius?
Notes:
The floating-point data type will be your friend here. Round your area answer so that no more
than 2 decimal places are shown when printing on the screen.
You can use 3.1415 for Pl; Think about this as a CONSTANT in your code.
For this part and especially part (b) below, think about componentizing your code. So one
gigantic main() is not a best practice and not what we want to see here. Remember what we
discussed about "procedural decomposition" and functions last week!

4. Directions: The question or incomplete statement below is followed by four suggested answers or
completions. Select the one that is best in each case.
The code segment below is intended to display all multiples of 5 between the values start and end, inclusive.
For example, if start has the value 35 and end has the value 50, the code segment should display the values
35, 40, 45, and 50. Assume that start and end are multiples of 5 and that start is less than end.
Line 1: i + start
Line 2: REPEAT TIMES
Line 3: {

- 4. Area of a Rectangle • Write a program that compares the area of two rectangles. You can do this several ways. one way is to add the length and width of each rectangle to get it's area and then compare the two areas together. • The program should ask for the length and width of two rectangles and then tell the user which rectangle has the greater area, or if the areas are the same. • The area of a rectangle is the rectangle's length times its width. Name the source code file yourName HW4.py. • Test and run the program. Capture the output console and save it as an image file named yourName HW4 output.jpg. • Submit the py and the image files through Canvas.

- Using C# in Microsoft Visual Studio create an application that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows:1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Do not display the computer’s choice yet.)2. The user selects his or her choice of rock, paper, or scissors. To get this input you can use Button controls, or clickable PictureBox controls displaying some of the artwork that you will find in the student sample files.3. The computer’s choice is displayed.4.

On a standard telephone, the alphabetic letters are mapped to numbers in the following fashion: A, B, and C = 2 D, E, and F = 3 G, H, and I = 4 J, K, and L = 5 M, N, and O = 6 P, Q, R, and S = 7 T, U, and V = 8 W, X, Y, and Z = 9 Create an application that lets the user enter a 10-character telephone number in the format XXX-XXX-XXXX. The application should display the telephone number with any alphabetic characters that appeared in the original translated to their numeric equivalent. For example, if the user enters 555-GET-FOOD, the application should display 555-438-3663.arrow_forward
